When someone asks ChatGPT, Claude, or Perplexity for a recommendation in your category — they're not finding you. They're finding your competitor. INDEXTER changes that.
The algorithms are different. The signals are different. You could be #1 on Google and completely invisible inside every AI. And AI is where high-intent buyers are going right now.
ChatGPT and Claude don't search Google when they answer questions. They draw from a knowledge layer built from training data, structured information, and real-time web context — and you're probably not in it.
When someone asks "what's the best [your product]?", AI picks a winner. It recommends 1 to 3 options and stops. If you're not in the top results of the AI knowledge layer, you don't exist to that buyer.
GEO — Generative Engine Optimization — is the fastest-growing channel in digital marketing. Early movers are locking in category dominance the same way early SEO adopters did in 2005. The window is closing.
No technical knowledge required. You tell us who you are — INDEXTER does the rest.
Fill out our intelligent intake form. Your name, your business, what you do, who you serve, what makes you different. 5 minutes. Plain language. No jargon.
INDEXTER generates your complete AI presence package: structured data files, a hosted AI-readable profile, and optional seeding across high-authority sources LLMs trust and train on.
Your profile gets crawled, cited, and registered. We cover 4 core AI platforms on Starter — and monitor up to 7 on Growth and Authority — reporting exactly how often you're being recommended and by which AI.
INDEXTER generates four core assets that put you on the map inside every major AI platform.
The most powerful thing we do. We host a structured, crawlable profile page for you at indexter.io/p/your-name — a single source of truth that every AI can find. Updated monthly. Permanently indexed. You don't touch your own website at all.
The emerging standard for telling AI who you are. A clean markdown file at your domain root that AI systems read when they browse your site. We generate and host it — you can also place it on your own site.
JSON-LD with full schema.org markup: Organization, Person, LocalBusiness, or Brand — whichever applies. This is the language Google, Bing, and every AI that uses real-time web search understands natively.
A YC-backed email API (YC W23) noticed something unusual: their #1 customer acquisition channel wasn't ads, SEO, or word of mouth. It was ChatGPT.
"When you ask how to send emails from your app, the default answer across basically every LLM is [this company]. Not the incumbent with 10,000 employees. The startup that optimized for agents."
The old go-to-market for dev tools was GitHub stars, Stack Overflow mentions, developer conferences. That world is over. Agents are now the decision-makers — and they choose based on who is most parseable, most structured, most agent-friendly. The companies who understand this first will own their categories for a decade.
Paste your URL. We'll crawl your site and score it across 4 dimensions: llms.txt, structured data, docs format, crawler access. See exactly how visible you are to AI — and what to fix.
Free, instant, no signup required.
In 2005, being early to SEO meant a decade of organic dominance. The people who moved first built moats that took competitors years to close.
We're at that inflection point for AI. The platforms are forming citation habits right now. The knowledge graphs are being built right now. The businesses that register their presence today will be the ones AI recommends for years.
INDEXTER exists to make that registration fast, affordable, and permanent.
